X-rays makes images of bones and gamma rays make images of the brain and kill center cells.
Hope this help and good luck

A surface completely surrounds a 3.3 × 10-6 C charge. Find the electric flux through this surface when the surface is (a) a sphe

KengaRu [80]

Answer:

Electric flux in a) , b) and c) is same which is 0.373 × 10 ⁶ N m²/C

Explanation:

given,

surface charge (q) = 3.3 × 10⁻⁶ C

to calculate electric flux = ?

a) radius = 0.76 m

area of sphere = 4 π r²

electric flux = $\dfrac{q}{\varepsilon}$

$\varepsilon = 8.85 \times 10^{-12} C^2/Nm^2$

electric flux = $\dfrac{3.3 \times 10^{-6}}{8.85 \times 10^{-12} }$

flux = 0.373 × 10 ⁶ N m²/C

electric flux in the other two cases will also be same as electric flux is independent of area

so, Electric flux in a) , b) and c) is same which is 0.373 × 10 ⁶ N m²/C

A magnet of mass 0.20 kg is dropped from rest and falls vertically through a 35.0 cm copper tube. Eddy currents are induced, cau

topjm [15]

Answer:

0.58 J

Explanation:

We know that Total energy is conserved.

Initial Kinetic energy + Initial potential energy = final kinetic energy+ final potential energy + dissipated heat energy

Initial kinetic energy = 0 ( magnet is at rest initially)

Initial Potential energy = m g h = (0.20 kg)(9.81 m/s²)(0.35 m) = 0.69 J

Final kinetic energy = 0.5 m v² = 0.5 ×0.20 kg × 1.10 m/s = 0.11 J

Final potential energy = 0

∴ Dissipated heat energy = (0.69 -0.11) J = 0.58 J

Greeley [361]

Answer:

Velocity of sound is 512 m/s

Explanation:

for first resonance condition we know that

$\frac{\lambda}{4} = L$

$\frac{\lambda}{4} = 0.40$

$\lambda = 1.6 m$

now the frequency is given as

$f = 320 Hz$

now to find the velocity of sound we have

$v = \lambda f$

$v = 1.6 (320)$

$v = 512 m/s$
